Application Data Magnecraft® PCB & Reed Relays
IntroductionPrinted circuit board (PCB) relays are compact relay devices used for power management in control system designs which require the relay to be mounted directly on the printed circuit board� They are used in applications where the relay must be small enough to be mounted on a printed circuit board� They must be easy to manufacture with the same machinery used in the printed circuit board line�
How Electromechanical PCB Relays WorkElectromechanical PCB relays consist of a coil, armature and contacts (see figure below)� When power is applied to the coil, the resulting magnetic field causes the armature to move and the contacts to open or close�
AdvantagesHigher contact ratings than reed relays and smaller than traditional plug-in relays �
A wider range of form, fit and function than reed relays �
UL recognized to meet industry standards for product safety and compliance �
How Reed Relays WorkReed relays consist of a coil wrapped around a sealed glass tube containing the reeds and contacts (see figure below)� When power is applied to the coil, the resulting magnetic field causes the reeds to move and the contacts to close (1)�
Advantages Highly reliable due to longer mechanical and electrical life than �electromechanical relays
Can switch about ten times faster than an electromechanical relay with �similar ratings
Small, industry standard packaging which does not require unique machinery �to populate
(1) Note that it is important to keep reed relays at a proper distance from each other because of the possibility of magnetic-interaction between them. Proper magnetic shielding must be used to contain stray magnetic fields. When installing reed relays into equipment, be aware of the devices in the equipment which can produce magnetic fields. Position the relays as far away as possible from any stray magnetic fields, and shield them to prevent false operations. A general rule is to space reed relays no closer together than 0.5 inches.
